This invention relates to an improved form of mounting device formounting cards, photographs, pictures and the like on a mounting sur-.face.

Heretofore mounting devices of this general character have been formedfor. the most part with a gummed or other type of adhesive surface onone side only thereof, and that is on the underside of the pocket whichreceives the corner of the card. The purpose of the adhesive on thisunderside of the pocket is to enable the mounting device to be securedto a mounting surface. It has also been customary in the past to omitany adhesive or gummed surface on the inside of the pocket therebyresulting in easy removal of the card from the mounting devices whichhold it.

This latter type of mounting device has dis-. advantages in that thecard may easily fall out of the mounting device and there is no way inwhich to mount the card permanently without the application of anadhesive directly to the corner of the card. There have been attempts toproduce a, mounting'device which may be folded from a blank in such away that, although the blank is gummed on one side only, gummed surfacesmay be presented both on the under and top sides of the pocket. Thisform of mounting device has the advantage of being able to be securedto. a mounting surface and at the same time securing the corner of acard in a pocket by merely moistening the gummed inner surface of thepocket. The blank from which such a mounting device must be formed,however, necessitates a complicated stamping action in the manufacturethereof, and thus was found to be expensive to produce.

The principal object of the present invention, therefore, is to providea mounting device for cards and the like which may be easily and eco,nomically manufactured.

Another object of the invention is to provide a mounting device whichmay be producedin elongated continuous strip of material and there;-after cut into predetermined lengths to form a body portion capable, ofbeing folded to form a pocket.

A further object of the invention is to provide a mounting device formedof a single strip of material having an adhesive applied to both sides Ithereof.

Still another object of the invention is to provide a mounting devicewhich includes a body portion formed of a single strip of material andayi -gamma or other type of adhesive surface on both sides thereof, andwherein a substantially triangular member is applied intermediate theends of the body on one side there; of thereby to provide a pocketbetween the, mem ber and the body. 7

A still further object of the invention is to provide a mounting devicewhich includes a body portion formed of a single strip of material hav;ing an adhesive or gummed surface on both sides thereof wherein asubstantially triangular shaped member is applied to one of the gummedsurfaces intermediate the ends thereof to provide a pocket, and wherebythe final device may be formed by folding the ends of the body along thesides) of the triangular member, whereupon the ends li e in overlappingrelation and may be secured together by means of the gummed or adhesive,sur faces thereon. f

Other objects and advantages of the invention will become apparentfromreading the following description taken in conjunction with theaccompanying drawing in which:

Fig. 1 is a plan view of a strip of material from which the presentmounting device may be formed; v

Fig. 2 is an enlarged longitudinal sectional view through the strip ofmaterial taken along the plane ofline 22 of Fig. 1;

Fig. 3 is a plan view of a length of material cut from the stripshown inFigs. 1 and 2 and from which the mounting device is formed by ioldingthere being an ornamental triangular member shown attached to the bodyof Fig. 3;

Fig. 4 shows the body of Fig. 3 partly folded Fig. 5 is an enlarged planview showing the strip in its final folded position to provide thefinished mounting device of the invention;

Fig. 6 is a fragmentary perspective view showing one of-the mountingdevices applied to a mounting surface; and t Fig. '7 is a section on theline 7-4 of Fig. 6 showing the device mounted on a sheet and securing aphoto print in position. p

In accordance with the present invention the. manufacturing cost thereofmay be sharply reducedbcause the individual body portion from which eachmounting device is formed is cut from a continuous length of stripmaterial such as shown in Figs. 1, 2 and 3. This strip. of ma terial isindicated generally by the numeral I and is provided along one edge.thereof with a plurality ofspaced inwardly extending. and sub-.stantially triangularly shaped notches 2.. The. opposite side of thestrip is provided with a like. number of triangular notches 3 extendingin-.. wardly. from the opposite edge of the. strip and. positioned sothat the apices. of the notches .2 and 3 will be in substantially thesame. transverse plane. The notches 3 are preferably.- slightlysmallerthan the notches 2. The upper and lower surfaces of the strip areprovided with an adhesive which is preferably a gummed surface asindicated at 4 and 5. The gummed surface has been found to be moresatisfactory because it presents a dry surface which can be easilyhandled and requires only moistening to bring out the adhesive qualitiesthereof.

A triangularly shaped member 6 may then be placed on the upper surfaceof the strip material as shown in Fig. 3. A plurality of such members 6are located in actual practice in spaced apart relation along the lengthof the continuous strip and are so located that the base of thetriangular member 8 is parallel with and coincident to one edge of thestrip. The apex of the member 6 is adapted to coincide with the apex ofthe corresponding notch 2 at the opposite edge of the strip. After thetriangular members have been applied, the strip is severed transverselyat a point intermediate adjacent members 6, whereupon a body gen erallyindicated at l is provided. If desired, the base of the triangularmember 9 may have a small triangular notch 8 in the base thereof tocoincide with the triangular notch 3 over which the member 6 is placed.This notch is used primarily for decorative purposes.

The body I then has end portions 9 and it at opposite sides of themember 5. In forming the mounting device from the body or blank '1', oneend If] is folded under the member 6 along one edge I I thereof, asillustrated in Fig. l. The next step is to then fold the end portion 9under the member 6 along the edge l2 of said member. The notch 2 permitsthe ends ii and If! to lie in overlapping relation after they have beenfolded as shown in Fig. 5. The fact that both sides of the body or blank'5 are provided with gummed surfaces enables the two end portions 9 andH) to be secured together in overlapping relation.

It is immaterial which of the end portions 9 or H) is folded underfirst, but in the illustration of Fig. 4, the upper gummed surface ofthe end it will be facing downwardly after it has been folded and theunder gumrned surface of the end 9 will be facing upwardly after thatend has been folded. Moistem'ng the overlapping gurnniecl portions ofthese ends will then enable the ends to be fastened together as shown inFig. 5 to complete the mounting device.

The pocket which is adapted to receive the corner of a card or othersimilar item is formed between the triangular member 6 and the overlapping folded ends 9 and iii. The ends 9 and H] are longer than thewidth of the body or blank 7 so that in their folded condition theyprovide a bottom wall of the pocket which is greater in length than theupper wall of the pocket formed by the member 6.

In actual use, the mounting device may be applied to a mounting surfacesuch as shown at l3 by moistening the under side of the bottom wall ofthe pocket. The pocket may then receive the corner of a card or the likeas indicated by the dot-dash lines 14 in Fig. 6. If it is desired tomount the card permanently, then the upper surface of the bottom wall ofthe pocket may be moistened, whereby to adhesively secure the corner ofthe card in place within the pocket. Customarily four such mountingdevices will be utilized for the mounting of a card or other such item,one for the reception of each corner thereof.

The advantages of such a construction as disclosed and described hereinare numerous. A principal advantage is the permanent security ofmounting afforded by the device, due to the twosided gumrning of theblank from which the device is made. Once a photographic print or cardhas been properly mounted on a mounting sur-- face by means of thepresent device, it is practically impossible to remove such print orcard therefrom, since the adhesive or gummed surfaces of the deviceadhere rigidly to both sides of the print or card and to the mountingsurface. An additional advantage is that the device obviates thenecessity of applying a paste or glue to the under side of the print orcard to mount the same permanently on a mounting surface. Anotheradvantage is that of economy of manufacture. This economical manufactureis the result of cutting the individual blanks from which the device isformed from a continuous strip of material. The device also has theadditional advantage of being decorative and pleasing to the eye becausethe triangular member 6 may be embossed with any suitable design.Furthermore, this member 6 may be formed of paper, plastic, or any othersuitable material and may also be formed of various colors.

Changes may be made in the form, construction and arrangement of partsfrom that disclosed herein without in any way departing from the spiritof the invention or sacrificing any of the attendant advantages thereof,provided, however, that such changes fall within the scope of the claimappended hereto.

The invention is hereby claimed as follows:

A mounting device of the character described, comprising a body formedof a single elongated strip of material having parallel edges, bothsides of said strip being gummed, said strip having a triangular notchin one side thereof, the base of said notch being in alignment with saidedge, a second triangular notch in the opposite edge of said striphaving the base thereof in alignment with the second edge, the apices ofsaid notches being in spaced aligned relation, a triangular memberapplied to one of the gummed surfaces of said body intermediate the endsthereof, the base of said triangular member being coincident with thesecond-mentioned edge of said strip, the apices of said first-mentionednotch and said triangular member coinciding and the converging sides ofsaid triangular member being in alignment with the sides of saidfirst-mentioned notch, the ends of said material being folded under saidtriangular member along the sides thereof and secured together inoverlapping relation by the gummed surfaces thereof, thereby forming apocket, the gummed undersurface of which is adapted to be secured to amounting surface and the gummed inner surface of which is adapted tosecure the corner of a card or pic ture received in said pocket.
